ROLLER BEARING,"

Application fiiedzrul 27,

This invention relates to improvements in roller bearings, and one ofthe objectsof the same is to provide an improved bearing of thischaracter whereby the radialandend 5 thrust willbe distributed to allofthe'rollers and transmitted. therethrough to the casing or box, and atthesame time the end plates of the casing will be relieved of straii'rand the necessity for use of balls for receiving end thrust will beobviated. I j i ,A further obj ect is to provide an improved bearing ofthischaracter-in which the rollers are ofa sectional construction,thereby facilitating in assembling the parts.

A further object is to provide an improved bearing of this character inwhich the parts are so arranged that all wear may be readily compensatedfor bythe adjustment of the sect-ions of therespective rollers withrelation to each other;

accomplishment of othernew and useful objects as will appear, theinvention consists in the features of novelty "in substantially theconstruction, combination and arrangement of the several parts,hereinafter more fully described andclaimed and shown in the,accompanying drawings illustrating this invention, and in which 1l,Figure 2, of a bearing of this character constructed in accordancewiththe principles of this invention.

Referring more particularly to the drawings thenumeral 1O designatesgcnerallya shaft to which is secured a bearing sleeve 11. The sleeve maybesecured to the shaft in any suitable manner but preferably by beingkeyed thereto asat112. g I

The be 'ng sleeve 11 may be of any desired length and diameter-and isdisposed within a: box orcasing having end walls 13 which the end wallsare'secured by means of suitable fastening devices 15., I

The shaft '10 may, be provided with suitable packing 16and packing nuts17 which are threaded on to the tubular portions18 of the respective endmembers 13. j

The periphery of the sleeve 11 tapers from the longitudinal center 19thereof toward the j outer ends so as'to form opposed frustro- To theattainment of these endsand the Figure 1 is a sectional view taken online, b I a the rollers and annular members 25 are held and acircumferential body portion 14, to I 1927. -Se1'ial No. 268,764.

aconical construction. The roller section 20 is p'rovided with anopening 22 extending longltudlnally therethrough and secured tothesection 21 is a rod or bar 23 which passes through the opening 22 inthe roller 20 and substantially fills the opening. The rod 23 projectsbeyond thefree extremity of the roller section 20 and threaded thereonisja nut or collar 24, by means of which the sections 2021 may besecured together end I to end. The smaller-ends the roller sections abuteach other so that the surface of the roller formedby the vsections 2021 taper from theouterends of the rollers sec-' tions towards thelongitudlnalcenter thereof to coincide with the peripheral surface ofthe bearing sleeve 11. v I c Any number of theserollers may be employedand the rollers of the series'are held togetherand in spaced relationfor rotation ,with respect to each other and upon the pe- 'riphery ofthe bearing sleeve 11, preferably by means of annular members 25 whichare provided with openings therein to receive trunnions26 on the ends ofthe rollers, and

against displacement with respect to each other by means of nutsorcollars 27 threaded upon the trunnions 26.

'Encompassing [the rollers is a floating sleeve 28, theinner surface ofwhich tapers fromthe outer ends towards a central point 29 asat'30-3l,"and with which surfaces the embodying sections 3536 engage. these sur-1 faces 33-34.

These latter rollersare preferably the same construction as the innerseries of rollers and each embodles. sections 85 36. The section 36 151provided withan'opening therethrough into which a rod 37secured to thesection 35, passes, and the 'rod projects beyondthe end of the rollersection 86, a nut or collar 38 being threaded upon the rod for holding Ithe sections together.

I The peripheries of" the roller sections- 3536 taperffrom the freeendstoward the longitudinal centerof the roller, so that peripheries oftheroller s'ections 35'3G r coincide with and rotate upon the respectiresurfaces 333 l, of the sleeve 28.

Theouter series'of rollers are secured together l against relative'displacemei'it by, means of an annular member 39 whichen-f compassesthe annular member 25, and transurfaces 43' 33 and 4% 34 with which afcontact. V c

' With this improved construction it will respective roller sections35.36 haverolling be manifest thatthe rollers of the respective serieswill be held against longitudinal movement inasmuch astheopposeddiverging and converging adjacent faces of the proximate partswill hold the rollers against longitudinal movement while the sameftrmethe parts will not be locked against a free rotary movement withrespect to each otherand also bodily about'each other.

7 With such a construction the end thrust [will not bedirected againstthe end walls of the bearing or casing but will be directed against thebodyportion of the casing with the further result that the use of ballsto compensate end thrust will be dispensed By reason of the sectionalconstruction of each of the rollers it will be manifest that, the partsmaybe readily assembled andby thearrangement and provision of theproXi-jmate faces of the adjacent parts in the manner asshown all wear may bereadily taken up. r 7 7 7 Should it benecessaryito grind any of thebearing faces it will bemanifest that by removingportionsof the abuttingends of the roller sections of the resiective rollers the rollers may beadjusted,tl1at is the parts of the rollers adjustedtowards'each othersufficiently to take up any wear'which might occur.
